answer:I have a fly swatter. It may take a while, but I can usually get it. I’m pretty good with it, and I can be patient. Failing that, I have fly paper, which works pretty good, but isn’t infailable. I don’t have anything against flies, but I really do not like maggots, and don’t want those in my place. So a fly intruder is either killed or chased outside, if possible. Fortunately, I have two cats who enjoy catching anything in my apartment…including the spiders, which sucks, I like spiders. Once I’ve had a real showdown with this mutant bumblebee but that’s another story…
